Abstract
The utility model relates to an electronic inductive charge level signalling device, belonging to the improvement of a charge level meter. A signalling control circuit is arranged in a housing. The front end of the housing is provided with an inductive probe, and the tail end of the housing is provided with an indicative luminescent diode. A signal inductive capacitor is connected with a composite tube amplifying circuit via a coupling resistance to drive a control a relay to work to generate charge level display signals, and meanwhile the external circuit can be controlled. The utility model has the advantages of convenient installation, reliable performance, and high sensitivity.
Description
The utility model relates to the improvement of level-sensing device.
Be used for instrument granular and powdery bin-level detection control at present, tuning fork level-sensing device, back and forth level-sensing device, ultrasonic level-sensing device are arranged, and these several level-sensing device ubiquities that volume is big, benzene heavy, adjust difficulty, unstable properties, defectives such as it is big to consume energy are made troubles to the user.
The purpose of this utility model provides a kind of material level that can detect automatically, indicate, and the induction type electronic charge level indicator that external circuit is controlled.
The utility model is by housing, the sender control circuit is formed, the sender control circuit is installed in the housing, the indication light emitting diode is positioned at the housing tail end, outside is provided with set nut, the elementary equalizing capacitance that is serially connected with of the power transformer of sender control circuit, and by coupling diode access bridge rectifier circuit, the secondary access bridge rectifier circuit of power transformer, and be provided with filter circuit of pressure-stabilizing, induction of signal electric capacity links to each other with the complex pipe amplifier by repeating resistance, the output terminal Access Control relay of complex pipe amplifier, and the pilot relay contact links to each other with the indication light emitting diode with external circuit respectively.
The utlity model has easy for installation, dependable performance, highly sensitive, characteristics such as cost is low.
Accompanying drawing 1 is the utility model contour structures synoptic diagram.
Accompanying drawing 2 is the utility model circuit theory diagrams.
Below in conjunction with accompanying drawing the utility model is further described, the utility model sender control circuit is installed in the shell body 1, shell body is the Rotary-table shape, tail end is provided with indication light emitting diode 2, the housing rear portion is processed with set nut 3, housing can be fixed on the storage bin container sidewall by set nut, or be vertically mounted in the feed bin from container top, the sender control circuit power transformer 4 elementary equalizing capacitances 5 that are serially connected with, link to each other with bridge rectifier circuit 7 by coupling diode 6, one static noble potential is provided for simultaneously complex pipe amplifier 10 and 11, power transformer is secondary to link to each other with the bridge rectifier circuit input end, operating voltage is provided for the complex pipe amplifier, at the bridge rectifier circuit output terminal and be connected to stabilivolt and filter-capacitor circuit 8, the electric capacity that measured medium and inductive head (the φ 30 bronze medal platinum of housing front end) form, link to each other with 11 with complex pipe amplifier 10 by repeating resistance, complex pipe amplifier out cut-in relay 12, the contact of relay links to each other with the indication light emitting diode with external circuit respectively, principle of work of the present utility model is such, the utility model is installed in the sidewall or the top of feed bin, when in streams is gone into feed bin, reaching required mensuration material level, material and induction type electronic charge level indicator head produce induced signal, at this moment complex pipe amplifier 10 and 11 conductings are in magnifying state, its output terminal directly drives relay 12 work, relay J
1-1The contact disconnects, and the light emitting diode that is connected in series with this loop, contact extinguishes, and indicates material and fills, and another contact of relay links to each other with external circuit simultaneously, can control material conveyor simultaneously and close, or link to each other with warning circuit, sends the material level alarm signal.
